while trying to create an rpm for the mp4h project, I jumped on the following problem:
- the toplevel configure has configure.ac - a subdir libltdl/ is copied in, which contains a configure.in - the rpm macro %configure will expand to a line like CFLAGS=$RPM_CFLAGS configure --prefix .... - the toplevel configure will call the the ltdl/configure using... configure sometarget --prefix... 'CFLAGS=$expanded_RPM_CFLAGS' and BOOM. Yepp, I can fix it while *not* using %configure with the extra CFLAGS settings. Anyway, interesting to see ;-) .. have fun, guido P.S. here are the last lines: config.status: creating config.h configure: configuring in libltdl configure: running /bin/sh './configure' i586-mandrake-linux-gnu --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/lib --localstatedir=/var/lib --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --with-modules 'CFLAGS=-O3 -fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586 -ffast-math -fno-strength-reduce' build_alias=i586-mandrake-linux-gnu host_alias=i586-mandrake-linux-gnu target_alias=i586-mandrake-linux-gnu --enable-ltdl-convenience --cache-file=/dev/null --srcdir=. configure: warning: CFLAGS=-O3 -fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586 -ffast-math -fno-strength-reduce: invalid host type configure: error: can only configure for one host and one target at a time configure: error: /bin/sh './configure' failed for libltdl sed: can't read confdefs.h: No such file or directory Fehler: Bad exit status from /my/rpm/tmp/rpm-tmp.16825 (%build)
